Sinus floor lift and augmentation is a common surgical procedure in modern dentistry. It aims to increase the amount of bone in the posterior maxilla, in the area of the premolar and molar teeth, prior to placement of dental implants. The procedure is performed in a per-oral approach; a mucoperiosteal flap is elevated, the lateral boney wall of the sinus is exposed and a window is cut with a surgical bur. The Schneiderian membrane (sinus periost) is separated and lifted from the bone and a bone graft material is placed into the newly created space. The graft material used can be an autograft, an allograft, a xenograft, an alloplast or a combination of these materials.
